Compared to the CSS transform attribute, this parser does not support units on numbers, and the default units are pixels and degrees.

• translate(100 100) - translates by (100, 100) pixels.
• rotate(45) - rotates by 45 degrees.

Supported functions:

Function	Description
matrix(a, b, c, d, e, f)	Matrix transform. See also donner::Transform
translate(x, y=0)	Translates by (x, y) pixels.
scale(x, y=x)	Scales by (x, y).
rotate(angle)	Rotates by angle degrees.
rotate(angle, cx, cy)	Rotates by angle degrees around (cx, cy).
skewX(angle)	Skews by angle degrees along the X axis.
skewY(angle)	Skews by angle degrees along the Y axis.

Commas between parameters are optional, and multiple transform functions may be composed for more complex transforms, such as rotate(45) translate(100 100).

Parameters

str	String corresponding to the SVG transform attribute.

Returns

Parsed transform, or an error.
